CODEX (music theory)

CODEX is a music theory system that organizes melodies and harmonies based on a grid of pitch relationships called the "code." It assigns numerical values to pitches and uses mathematical patterns to analyze and generate musical compositions. This approach helps musicians understand the structure and progression of music by revealing underlying connections between notes, scales, and chords. Essentially, CODEX provides a framework for studying music's logical relationships, enabling more precise composition, analysis, and improvisation, especially in complex musical contexts.
